Rebound booster for shoe soles

Abstract

The invention relates to a rebound power assisting device for a shoe sole. The rebound power assisting device comprises power assisting bodies assembled in the shoe sole, the power assisting bodies are constituted by a plurality of unit bodies, the multiple unit bodies are sequentially connected to be arranged in a U shape, each unit body is an elastic part which is in an arc shape and bent into a C shape, and the top faces of the two ends of each unit body are connected with the shoe sole; the power assisting bodies are constituted by heel portions and sole portions, the unit bodies constituting the heel portions of the power assisting bodies are distributed in left-right mirror symmetry, and the same ends of the unit bodies at the left side and the unit bodies at the right side are integrally connected through connection straps. By means of the structural mode of the unit bodies and the power assisting bodies, the rebound power assisting device can have good deformation ability, improvement of the shock alleviating effect of the shoe sole is facilitated, and antiskid and anti-side-turning capability of the shoe sole in the left-right side direction can also be improved; the two ends of each unit body can generate inclined forward rebound force to the shoe sole, the rebound rate of the force reaches 35-52%, and forward thrust assisting power is provided for an athlete.

Description

technical field [0001] The invention relates to a component part of a shoe sole, in particular to a rebound assisting device for a shoe sole. Background technique [0002] When exercising, the impact force on the heel of the athlete is three times that of his own body weight. This force will generate shock waves that are more harmful to people, causing damage and pathological changes to tissues such as bones, muscles or joints. For this reason, having the sole of good cushioning function is one of the important ways to solve this problem. The current cushioning soles are mostly made by adding elastic cushioning devices such as air cushions, silicone cushions, and springs, or using materials with large deformations (such as EVA) to make soles, or through cushioning such as honeycomb structures and cushioning protrusions. Structure and other methods to achieve the purpose of cushioning. They either have complex structures, cumbersome production processes, or have large soles...
